Abstract (en)
A direct fuel injection type internal combustion engine having a combustion chamber formed with a recess in which intake air is introduced and swirled. A swirl injector is arranged such that its central spray axis does not intersect the central axis of the recess but extends at an inclination thereto. The maximum distance between the facing sides of the recess is set at 25 to 65 mm. The distance between the axis of sprays of the swirl injector and a second plane intersecting, at a right angle, a first transverse plane containing the location of the maximum distance D of the recess, the second plane being parallel to the axis of sprays of the swirl injector and containing the center of the recess on the first transverse plane, is set at 6 to 20 mm. The angle contained between the axis of sprays of the swirl injector and the first transverse plane is set at 40 to 70 degrees.
